The "Five Tinea" (Wu Xuan) refers to damp tinea, stubborn tinea, wind tinea, horse tinea, and cow tinea. (Both scabies and tinea are caused by heat and dryness in the blood level, leading to wind-toxin attacking the skin. Lesions that are superficial are called scabies, while those that are deep-seated are called tinea. Scabies is often accompanied by heat, whereas tinea is often accompanied by dampness.)
Fangfeng Tongsheng San (Saposhnikovia Universal Relief Powder): Treats tinea and scabies. Remove Mangxiao (Mirabilite) and Dahuang (Rhubarb) from the formula, and add Fuping (Duckweed) and Zaojiaoci (Gleditsia Spine). (See the "Stroke" chapter for the full formula details.)

Preparation and Administration: Coarsely crush the herbs. Take two doses, add two stalks of Congbai (Scallion White) and 50-60 grains of Douchi (Fermented Soybean), decoct until one-eighth remains. Drink hot to induce sweating.

For "Goose Palm Wind" tinea (hyperkeratotic tinea manuum), characterized by peeling skin layers, itching, and pain, washing with this prescription leads to immediate cure.

Note: Do not scratch the tinea sore open. Avoid contact with water for 7-8 days post-treatment. This yields miraculous effects.
Sublimation Process:
Place one small porcelain jar. Seal with salt mud. Put Xionghuang (Realgar) inside. Cover with a lamp saucer, tie tightly with iron wire, and seal the surroundings with wood ash, charcoal, and mud. Slow-fire roast for half an incense stick's duration. Collect the sublimated yellow substance from the underside of the saucer for use.
